In a wood panel construction method in which building panels are assembled to form a building, a floor, a wall, and a roof are constructed by connecting a plurality of unit panels.

[0003] In this case, if all the building panels are assembled on the floor, wall, and roof on site, there is a problem that the construction is troublesome and the construction period is prolonged. Further, in order to increase the assembly accuracy, the skill of the operator was required.

[0004] Therefore, a plurality of unit panels are pre-assembled in a factory in advance, the formed architectural panels are transported to the site, and the pre-assembled architectural panels are assembled to simplify the on-site work. Attempts have been made to shorten the construction period and improve the accuracy, thereby improving production efficiency.

[0005] However, when building panels conveyed from a factory are hoisted on site by a crane or the like, the following problems occur.

[0006] For example, in the case of a roof panel or a floor panel, the building panel suspended by a crane or the like is lifted substantially horizontally in advance so that installation is completed by lowering the building panel as it is. This will be described with reference to FIG. 5 taking the case of a roof panel as an example. The roof panel 100 is formed by connecting a plurality of unit panels 120 in a plane direction. 160 is attached. And this hanging hardware 1
A hanging jig 170 is attached to the ceiling 60, and a hanging jig 164 of the hanging jig 170 is hooked on an eaves-side end of the roof panel 100. Can be

In this case, since the roof panel 100 is long in the vertical direction, the load is concentrated near the center in the longitudinal direction. Therefore, the unit panel 1 located near the center
The roof panel 100 had to be reinforced in order to prevent the joints 150 of 20 from being bent in the middle.

In order to improve the mechanical strength of a building panel formed by joining a plurality of unit panels,

The unit panel 20 includes a plurality (three in this embodiment) of vertical core members 30 arranged in parallel at a predetermined interval.
And the vertical core material 3 at the upper and lower positions of the vertical core material 30.
A frame formed by the two horizontal core members 40 arranged between 0, and a plurality (in the present embodiment, unit panel 20
a is one and three unit panels 20b are three).

The three vertical core members 30 are arranged on both sides of the unit panel 20, and form the horizontal core member 40, the outer frame vertical core members 32, 32 constituting the outer frame 22, and the outer frame vertical core members 32, 32. And a middle vertical core member 34 disposed between them. A plurality of bolt holes 54 for joining the large-sized roof panels 10 in the direction of the horizontal core member 40 are formed through the side surface of the outer frame vertical core member 32 at predetermined intervals.

In addition, the large-sized roof panel 10 includes the vertical core material 3.
Since the connecting reinforcing plate 62 is attached to the side surface of the vertical core member 30 at all positions where the 0 and the joining-side horizontal core member 42 face each other, the reinforcement becomes more sufficient, and a single sheet from the ridge portion to the eaves portion. Sufficient mechanical strength is ensured even for a large roof panel that covers up to the part. Therefore, it is possible to reliably prevent the middle bend during the lifting movement, and it is not necessary to use any reinforcing means other than the connection reinforcing plate 62, for example, a metal fitting for reinforcement. Further, since the connection reinforcing plate 62 is fitted into the gap 60 formed between the vertical core member 30 and the joining-side horizontal core member 42, the panel can be installed without requiring a laborious work such as digging. There is no obstruction during transportation, and even if the panel has a finishing material, it does not damage the finishing material.
